8、 Ontario and Quebec Chapter, and the Structural Division of the Canadian Society for Civil Engineering, sponsored a three- day conference in Ottawa on the use of superplasticizers in concrete. Selected papers from the symposium were published as American Concrete Institute special publication SP-62.
9、 In 1981, CANMET in association with the above organizations, spon- sored a second three-day international conference in Ottawa on the use of superplasticizers in concrete. The proceedings of the conference were published as American Concrete Institute special publication SP-68. In October 1989, CAN
10、MET in association with the American Con- crete Institute and the AC1 Eastern Ontario and Quebec Chapter sponsored the third three-day international conference in Ottawa. The purpose of the third conference was to review the progress made since the meetings in 1978 and 1981; and to bring together re
11、presentatives of the chemical admixtures, cement, and concrete industries to exchange information and to delineate the new areas of needed research. The scope of this conference was expanded to include chemical admixtures other than superplasticizers. The proceedings of the conference were published
12、 as American Concrete Institute special publication SP-119. In October 1994, CANMET in association with the American Con- crete Institute sponsored the fourth conference on the subject in Montreal, Canada. The objective of this conference was to bring to the attention of the concrete community the n
13、ew developments in chemical admixtures since the last conference in 1989. A total of 44 papers from more than 12 coun- tries were received and reviewed by an expert panel of AC1 reviewers, and 25 were accepted for publication in the proceedings of the conference. The proceedings were published as Am
14、erican Concrete Institute special publica- tion SP-148. The co-operation of the authors in accepting the reviewers suggestions is greatly appreciated. Particular thanks are extended to the members of the review panel for their contributions towards the publication of this volume, The help and assist
